I kinda thought your hand might be in this. Good on this group for thinking outside the box.Better than the potential Cummins calibrations is the group of owners ? that have developed an emulator to have in ones toolbox for when them inevitable happens. The development is done and it’s currently undergoing beta testing.
This is really good to know. Got these 3 codes 3 times on our trip (5500 miles). Never derated. Matter of time I guess. I w3as always able to get it where it says "No faults". No check engine light,no codes. Newmar says this is a Spartan issue. Do I take it to a Spartan service center? Your thoughts? I live in Los Angeles.Here is an update reported to be to from the EPA that was posted by a forum member on another forum.
Statement Regarding Failed Diesel Emission Fluid (DEF) Sensors
EPA and the California Air Resources Board (CARB) have been working with the manufacturers of diesel vehicles and engines to address an issue related to the ongoing shortage of computer chips and the impact that has had on the availability of certain replacement parts. One part in particular, a sensor that monitors the quality of diesel emissions fluid (DEF), has been of concern because the failure of the part can lead to the vehicle being unable to operate. The Engine Manufacturers Association (EMA) on behalf of its member companies has proposed an industry wide approach that would provide a software solution for vehicles with failed parts to enable them to operate temporarily while the industry works to produce more replacement parts and that, long term, would provide replacement parts through a recall program. EPA and CARB have reviewed the proposed approach and believe it is appropriate for the companies to implement the proposed solution going forward as quickly as possible.
The manufacturers must still develop new software code and test it to ensure the software can be installed on vehicles in the field. The companies expect that they will be able to begin fixing some vehicles with failed sensors as soon as this week. The companies will also make available a similar software update for vehicles whose sensors have not failed but are among a group of vehicles where such a failure could be expected to occur to prevent a sensor failure from disabling the vehicle. This updated software is likewise expected to be available to service centers in the coming weeks.
